Title: Soldering method
Inventor: NISHIMORI NAOKI
IPC: H05K3/34
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a soldering method by which the lands of two or more circuit boards can be soldered to each other by combining the circuit boards in a double cross state and the fluctuations of the joining strength and reliability can be eliminated. SOLUTION: In a soldering method in which conductor patterns are joined to each other by performing soldering at every set of lands to be joined, one or more sets of lands 11a and 11b to be joined are arranged at the corners of a double cross through a process of forming solidified solder 6 on the lands 11a and 11b for joining conductor patterns and combining circuit boards in a double cross state and the lands are joined to each other in one bodies at every set by melting the solidified solder 6 on the lands 11a and 11b arranged at the corner sections of the double cross by heating in a process of mounting electronic parts on circuit boards 1a and 1b.

Title: Dynamic pressure bearing device
Inventor: SAKATANI IKUNORI
IPC: F16J15/43
Filed: 1990-03-22
Abstract: PURPOSE:To prevent the off-tracking of a magnetic head opposed to a magnetic disk and improve durability by forming both side faces of a collar part, larger in diameter than radial receiving faces provided at two places of a shaft, into thrust receiving faces, and disposing magnetic fluid seals on both outer sides of radial bearings. CONSTITUTION:A thrust bearing S is disposed between radial bearings R. Accordingly, even if thermal deformation is generated to a shaft 23 and a hub 29 due to ambient temperature change, the distance between two vertical thrust bearing faces 35, 35 is made small to minimize the change of a thrust bearing clearance 34. The axial spacing between the bearings R at two places is further widened to enlarge moment rigidity. The off-tracking of a magnetic head opposed to a magnetic disc fitted at the hub 29 is thereby prevented to cope with densification effectively. A magnetic fluid seal 40 prevents lubricant from being scattered outside from a radial bearing clearance 31 at the startup/stop time of a housing 28 and also prevents the evaporation of lubricant outside, and thus durability can be improved.

Title: Zoom finder device and zoom lens camera
Inventor: HASUSHITA YUKIO
IPC: G03B13/12
Filed: 1990-03-22
Abstract: PURPOSE:To accurately display the photographable range by changing the visual field of a finder by using both of the change of size of a visual field frame by a visual field frame variable mechanism and the change of finder magnification by a variable power lens. CONSTITUTION:2nd and 3rd lens groups L2 and L3 are movable variable power lens groups, and the visual field frame variable mechanism 30 is provided on the image-formation surface of an objective optical system. When the focal distance of a zoom photographing optical system T changes, for example, in the range of 28-70 mm, the finder magnification is not changed but the size of the visual field frame 50 is changed from large to small in a specified focal distance range, for example, 28-35 mm. In the remaining focal distance range(35-70 mm), the size of the frame 50 is not changed but the finder magnification is changed in accordance with the focal distance of the photographing optical system. Thus, not only the photographable range but also the state of the focal distance are accurately shown to a user.
